The reaction against archaeological explanations relying on invasion and migration was part of the processualist critique in the 1960s. Only recently have archaeologists like Kristiansen argued that as migrations can be traced in the historical record, some archaeological method of identifying them must be found. This volume comes from a 1993 TAG session and pursues this issue.
